If you are a Christian, is Romney destined for Hell?

This is a question only. If you are a Christian, is it your belief that Mormons are destined to go to Hell because of their beliefs? If you believe this, how can you vote for him?

I disagree with the idea as I have never been able to get my head around the idea that Gandhi is bound to the fire because he did not accept Jesus, but I am interested in other opinions and the logic followed by those who believe Romney is going to end up in Hell and will still vote for him in part because he shares their values. Wouldn't that be a vote against Jesus?
